Eddie Lacy, wearing sunglasses on the way out of the locker room, not available for comment because he's being checked for a concussion

ESPN's Darren Rovell had an interesting note on Lacy's helmet:

Riddell SpeedFlex helmet, which says it reduces impact force and was on Eddie Lacy tonight, hits the market on Oct. 1.

Lacy had run for just over 30 yards against the vaunted Seattle defense prior to the injury.

The former Alabama star was named the league's Offensive Rookie of the Year last season after rushing for 1,178 yards and 11 touchdowns. He was also selected to the 2013 Pro Bowl squad. However, Lacy did suffer a concussion last season, which makes this injury even more concerning.

There were plenty of people expecting a big jump from the running back in his second year, including NFL Network's Stacey Dales:

I think it will be tougher, because it's not like you're surprising everyone. When you first come in, people doubt you. They know what you did in college, but they don't know if it will translate to the next level. But once you get that year in and people see what you've done and it's no longer surprising, they're going to prepare for you the way they prepare for whoever else is good at that position.

While he has had some success, this latest injury is at least a bump in the road. If he can make his way back onto the field sooner rather than later, the team should trust him to step right back into his spot in the lineup.

In the meantime, James Starks will likely take over the starting job for as long as Lacy is sidelined. The veteran finished with 493 rushing yards last year in relief of the rookie, and his past experience as a spot starter should make this transition fairly seamless.

The Packers should be just fine in Lacy's absence with star quarterback Aaron Rodgers and a long list of talented receivers in tow—at least in the short term.
